I want to fix the minimum mesh size when zooming out the camera

Let’s say there is one OrthographicCamera, OrbitControl, and Mesh.

When zoom out, the mesh gets smaller and smaller and then disappears.

At this time, I want to set the minimum size of the mesh when it zooms out and becomes smaller.
Based on screen px.

Does anyone have any ideas on this?

Limit zoom distance / camera distance from the target?

No, that’s not the way.

I don’t want it to disappear from the screen.
And zooming out should be unlimited.
